United States Patent O 3,388,958 HOT LATHER SHAVING BRUSH ATTACHMENT FR AERUSGL DISPENSER .lohn J. Modla, 46 .iones St., `Iersey City, NJ. 07306, now by change of name, William D. Johnson Filed Aug. 15, 1966, Ser. No. 573,165 9 Claims. (El. dill-2) ABSTRACT F THE DISCLOSURE Hot lather shaving brush attachment for aerosol shaving lather container comprising housing, means on one end of housing for detachably mounting lhousing on can, bristle bearing means, means for detachably mounting bristle bearing means at other end of housing, heat conductive conduit means in housing for communicating outlet of aerosol can with bristles, means for heating conduit means, and means in housing for actuating dispensing mechanism on aerosol can.

This invention relates generally to shaving accessories. More specifically, it relates to shaving brushes adapted to dispense heated lather from an aeroso1 can which contains shaving lather under pressure.

Attachments for heating lather as it is dispensed from a conventional aerosol can of shaving lather are known. Shaving brush attachments for aerosol cans of shaving lather are also known. In my copending patent applications Ser. Nos. 437,660, filed Mar. 8, 1965, and 476,357, led Aug. 2, 1965, I disclose shaving brush attachments which are particularly suitable for use in conjunction with a variety of commonly used aerosol shaving cream cans,

I have now conceived a device which provides even greater convenience and comfort for the shaver by cornbining in a unique manner and in a single device, means for transmitting heat to lather as it is dispensed from an aerosol can and for dispensing the heated lather from a shaving brush attached to the can.

Accordingly, it is an object of this invention to provide an attachment for an aerosol shaving lather dispenser wherein the lather may be heated and transferred to the bristle of a shaving brush for convenient application of instant heated lather by the shaver.

Another object of the invention is to provide a shaving brush attachment for dispensing heated lather from an aerosol container, which attachment can be manufactured economically, is particularly ecient and easy to use, can be readily cleaned, conveniently stored, and reused on a number of aerosol cans.

Another object is the provision in a single unit of a device whereby lather may be heated and dispensed from an aerosol shaving lather dispenser through the bristles of a shaving brush.

In accordance with the present invention there is provided a device which is removably attachable to the top of an aerosol dispenser such as a can of pressurized shaving cream. Means are provided on the device for actuating the dispensing mechanism of the aerosol can. Conduit means are provided for conducting dispensed lather from the outlet to the bristles of a shaving brush at the opposite end `of the ydevice from the end which is attached to the dispenser. And a heat sink is provided for bringing a heated fluid, such as hot Water, in contact with the conduit containing the shaving lather to thereby heat the lather as it is transported from the dispenser outlet to the shaving brush.

In the several illustrated embodiments, various means are shown for attaching the device to the aerosol can and for actuating the dispensing mechanism thereof. In addi- 3,388,953 Patented .lune 18, 1968 ICS tion, various arrangements of conduit means and heat sinks are also shown.

The above and other objects, characteristics and features of the present invention will be more fully understood from the following description taken in connection with the accompanying illustrative drawings.

FIG. 14 is a sectional view taken along the line 14-14 of FIG. 13.

Referring now to the drawings in detail, and with particular reference to FIGS. 1 and 2, a hot lather shaving brush attachment 20 is illustrated comprising a housing 22 having a base 24. The base 24 is made of somewhat resilient material so that it can be removably mounted, eg., spring pressed, on the rim 26 of an aerosol can 28. The opposite end of housing 22 comprises an internally threaded receptacle adapted to receive therein an externally threaded cup 31 on which are mounted a plurality of bristles 30.

As shown in FIGS. 2 and 3, a disc 32 is mounted within housing 22 a short distance above the hase 24. Disc 32 may be made of any suitable flexible material such as polyethylene or spring steel and may he manually depressed to engage a dispensing tube 34 on the top of the can 28. By depressing disc 32, tube 34 is actuated to release pressurized foam therethrough, the means of release being well known in the art.

Centrally located on the bottom of disc 32 is an annular collar 36 of slightly greater inner diameter than the outer diameter of the dispensing tube 34. Collar 36 deiines the inlet end 38 of a conduit 40, which conduit di) extends to its outlet end 42 through a central aperture 41 in cup 31 in communication with bristles 30. As can be seen from FIG. 2, when disc 32 is depressed, collar 36 embraces tube 34, bringing the inlet end 38 of conduit 40 into communication with the outlet end of tube 34. When disc 32 is further depressed, a shoulder 37 projecting inwardly from the upper part of collar 36 engages the top of tube 34 to thereby depress tube 34, thus actuating the foam release mechanism.

As shown in FIGS. 2 and 4, conduit 40 is disposed within a central cavity 42 in housing 22 and is wound in a coil in the upper portion of said cavity 42. Housing 22 has a cut-out portion 46 (FIGS. l and 2) therein in communication with the portion of cavity 44 above disc 32 and below the coiled portion of conduit 40. As will be more fully explained below, cut-out 46 provides access to cavity 44 for manual operation of the attachment by depressing disc 32. In addition, a second cut-out 47 may be provided in the rear of housing 22 for contacting conduit 40 with hot water within cavity 44.

To operate the hot lather shaving brush attachment of the present invention, the attachment 20 is rst secured to the aerosol can 28 by mounting base 24 of the attachment 20 on rim 26 of the can 28 as shown. Then housing 22, which is made of any suitable heat conductive material, such as copper alloy or the like, is contacted with a hot fluid, desirably hot tap water, for a short period of time, e.g., to 30 seconds. This serves to heat conduit 40 which is also made of heat conductive material and is in heat conducting relationship with housing 22. Then, one may actuate the dispensing tube 34 of the can 28 by inserting a finger through cut-out 46 and depressing disc 32. Shaving lather is thereby released from tube 34, passes through inlet 38 into the conduit 40, through heated conduit 40 wherein the shaving cream is'heated by contact with the walls thereof, and hence, through outlet 42 onto the bristles 30.

When the desired amount of hot shaving cream has thus been conducted to the bristles 30, the disc 32 is released and the linger withdrawn through cut-out 46. The user is then in a position to apply the heated lather directly from the brush. It is thereafter a simple matter to wash the brush free of lather with running water. If desired, attachment may be removed from the can after use and conduit 40 cleaned by passing running water therethrough through inlet 38.

Referring now to FIGS. 5-7, wherein similar parts are given similar reference numerals, a second embodiment of the invention is illustrated, the embodiment of FIGS. 5-7 differing from that illustrated in FIGS. 1-4 only in the construction of the conduit means 40a communicating inlet 38 with outlet 42. As shown, conduit 40a extends along the inner side of housing 22 in a double wall arrangement formed by an inner wall 23. Again, to provide for greater ease in contacting inner wall 23 with hot water during the preheating of conduit 40a, a second cut-out 47 is provided in the rear of housing 22. Otherwise, the detailed description and operation procedure hereinbefore provided with respect to the embodiment of FIGS. 1-4 is applicable as well to the embodiment of FIGS. 5-7.

FIG. 8 illustrates a third embodiment of the invention, similar parts again being given similar reference numerals. Essentially, the embodiment of FIG. 8 is virtually identical to that illustrated in FIGS. 1-4, except that base 24b is wider than in the first embodiment and is adapted to be mounted on an outer rim 26b of the aerosol can. Further description of this embodiment and the operation thereof is not considered necessary inasmuch as the detailed discussion of the embodiment of FIGS. 1-4 can be applied thereto.

In FIG. 9 there is illustrated yet a fourth embodiment of the invention. As before, similar parts are given similar reference numerals. In this embodiment, cup 31 is provided at the lower end thereof with a hollow cylindrical extension 48 having a central cavity 44c therein.

Cylinder 48 serves to replace disc 32 of the earlier embodiment as the means for actuating dispensing tube 34. This is accomplished by screwing down cup 31 until the bottom of cylinder 48 comes in contact with and depresses tube 34. Cylinder 48 has at the bottom thereof inlet means 49 for communicating tube 34 with conduit 40e, which conduit, in the embodiment of FIG. 9, is formed by a double wall arrangement alongthe inner side of cylinder 48 analogously to conduit 40a of the embodiment of FIGS. 5-7. As will be seen, conduit 40C communicates with the bristles 30 through the central aperture 41 in cup 31.

Yet a fifth embodiment of the invention is illustrated in FIG. l0, wherein similar parts are again given similar reference numerals. The embodiment of FIG. 10, as can be seen from the drawings, is very similar to that illustrated in FIG. 9, the essential difference being that in the embodiment of FIG. 10 the conduit 40d comprises a coiled tube similar to that illustrated in FIGS. 2, 4 and 8, which conduit 40a', however, is disposed within the hollow internal portion of cylinder 48. As in the embodiments illustrated in FIGS. 2 and 8, conduit 40d communicates with bristles 30 by means of outlet 42d which extends through the central aperture in cup 31.

Referring now to FIGS. 11 and 12, there is illustrated a sixth embodiment of the invention, adapted to be used with another type of aerosol can 28e. As illustrated, aerosol can 28e has the usual internal foam release mechanism but the dispensing tube 34 of the earlier embodiments is not present. Basically, the device shown in FIGS. l1 and 12 is very similar to that shown in FIG. 8, and includes the foam release mechanism comprising an actuator disc 50 mounted within the cavity 44 of housing 20e, a hollow plunger 51 extending downwardly from the disc 50 and communicating with a lateral dispensing tube 52 carried on the under side of disc 50 for dispensing the foam from the can into inlet 38e of conduit 40e at the juncture 39 upon actuation of the release mechanism. As illustrated, plunger 51 is provided with a V- notch 53 at the bottom thereof to assure proper flow of the released shaving cream through the plunger 51.

As will be seen by a comparison of the drawings, conduit 40e is otherwise the same as conduit 40 of FIG. 8, being coiled within the cavity 44 of housing 20e. Base 24e is mounted on the outer rim 26e of can 28e in the same manner as base 24b is mounted on rim 26b in the embodiment of FIG. 8, and all of the remaining elements of the two devices are likewise similar. Naturally, the operation of the two devices is also substantially the same, actuation of the foam release mechanism being elected by depressing the disc 50 and its associated plunger 51. The basic diiferenoe in structure is that the dispensing tube 34 of the can shown in the embodiment of FIG. 8 has been replaced by plunger 51 mounted on the device of the present embodiment.

In FIGS. 13 and 14 there is illustrated yet a seventh embodiment of the invention, adapted to be used with an aerosol can 28f which has another common type of foam or lather release mechanism. As can be seen from FIG. 13, the dispensing tube 34)c of can 28j extends outwardly from the top of can 28f and has a coiled spring 54 mounted thereon. Release of pressurized lather is etfected by lateral displacement of tube 34f, the means of release being well known in the art. Spring 54 serves to normally bias tube 34] in a vertical, undisplaced position.

As shown in FIGS. 13 and 14, conduit 40)c is wound Within cavity 44f in a vertical, cylindrical coil of greater internal diameter than the outer diameter of tube 34j, the inlet 38)c of conduit 40 being located centrally within this vertical cylinder and being adapted to be inserted into tube 34f when the attachment is mounted on the can. That is, when the attachment is mounted on the can, tube 34j is received within the hollow portion of the cylinder formed by the winding of conduit 40j and in turn receives inlet 38j therein. Accordingly, the lateral displacement of tube 341 to actuate the lather release mechanism is effected by pushing the coiled conduit tif slightly to one side. Lather is thereby released through tube 34f and inlet 38f into conduit 4tlf, which conduit communicates with bristles 30 in the same manner as in the other embodiments. It will be observed that the device is otherwise similar to the previously described embodiments. Thus, conduit 46j is heated in like manner as the conduits of the other embodiments, and base 24f is mountable on inner rim 26f of can 28jc as in the embodiment of FIGS. l-4.
